Hiii..
I need an urgent help regarding a DC DC power supply with input 18-60 Volt DC, Output 12V, 3 Amps using LM5088. I am not getting desired output and sometimes IC burns out around 40-60 Volt input..

Is your input voltage ac? Can you post some waveforms? Be sure to include Vin at M1 and the SW node as well as Vfb to start. There are probably some big issues with your layout. The input filter caps need to be close to M1.
